 * Najpierw możliwe do uzyskania funkcje załączania
4
5
    Załączenie chwilowe (momentary) - przekaźnik jest załączony tak długo jak długo naciskany jest klawisz pilota - nadawany kod
6
    Przełącznik (toggle) - przekaźnik jest załączany /wyłączany przy kolejnych naciśnięciach tego samego klawisza - nadajemy ten sam kod
7
    Włącz/wyłącz (latched) - przekaźnik jest załączany jednym kodem a wyłączany innym
8
    Włącznik czasowy 5 sek - po naciśnięciu pilota następuje załączenie przekaźnika na czas 5 sek
9
    Włącznik czasowy 10 sek - załączenie na czas 10 sek
10
    Włącznik czasowy 15 sek - załączenie na czas 15 sek

Programowanie
13
Niby opisane jest to na stronach dostawców - ale nie do końca - więc pełen opis programowania. Zalecane rozpoczęcie od punktu 8 - KASOWANIE
14
15
    Załączenie chwilowe (momentary) - naciskamy 1x przycisk programowania (potwierdzenie naciśnięcia krótkim błyskiem LED). LED po chwili włącza się na stałe na 8-10 sek. W tym czasie układ gotowy jest na przyjęcie nowego kodu. Wysłany kod zapamiętany jest w pamięci a potwierdzeniem tego jest podwójne "mrugnięcie" LEDa. LED gaśnie . Koniec procedury.
16
    Przełącznik (toggle) - naciskamy 2 x przycisk programowania. Dalej jak w pkt. 1
17
    Włącz/wyłącz (latched) - naciskamy 3 x przycisk programowania (potwierdzenie naciśnięcia krótkim błyskiem LED). LED po chwili włącza się na stałe na 8-10 sek. W tym czasie układ gotowy jest na przyjęcie nowego kodu. Wysłany kod zapamiętany jest w pamięci a potwierdzeniem tego jest podwójne "mrugnięcie" LEDa. LED pozostaje włączony Układ czeka na odbiór drugiego kodu. Po jego wysłaniu jest znowu podwójne "mrugnięcie" LEDa. LED gaśnie. Koniec procedury.
18
    Włącznik czasowy 5 sek - naciskamy 4 x przycisk programowania. Dalej jak w pkt. 1
19
    Włącznik czasowy 10 sek - naciskamy 5 x przycisk programowania. Dalej jak w pkt. 1
20
    Włącznik czasowy 15 sek - naciskamy 6 x przycisk programowania. Dalej jak w pkt. 1
21
    Włącznik czasowy 15 sek - naciskamy 7 x przycisk programowania. Dalej jak w pkt. 1
22
     KASOWANIE - usuwanie z pamięci wszystkich kodów. Nacisnąć 8 x przycisk  . Każde naciśniecie sygnalizowane jest błyśnięciem. Po 8 naciśnięciu następują trzy mignięcia i pamięć kodów jest wyzerowana. Można też skasować pamięć naciskając przycisk raz przez ok 8 sek . Po puszczeniu przycisku LED zapali się na ok 3-4 sek i zgaśnie. Efekt działania ten sam.
23
24
Wszystkie te funkcje działają równolegle bo układ może zapamiętać do 50 kodów! Dodatkowo w trybie włącznika czasowego można skrócić czas załączenia poprzez wysłanie kodu WYŁĄCZ z wcześniej ustawionej funkcji latched.

@brief general exception of the @ref basic_json class
616
617
This class is an extension of `std::exception` objects with a member @a id for
618
exception ids. It is used as the base class for all exceptions thrown by the
619
@ref basic_json class. This class can hence be used as "wildcard" to catch
620
exceptions.
621
622
Subclasses:
623
- @ref parse_error for exceptions indicating a parse error
624
- @ref invalid_iterator for exceptions indicating errors with iterators
625
- @ref type_error for exceptions indicating executing a member function with
626
                  a wrong type
627
- @ref out_of_range for exceptions indicating access out of the defined range
628
- @ref other_error for exceptions indicating other library errors
629
630
@internal
631
@note To have nothrow-copy-constructible exceptions, we internally use
632
      `std::runtime_error` which can cope with arbitrary-length error messages.
633
      Intermediate strings are built with static functions and then passed to
634
      the actual constructor.

@brief exception indicating a parse error
669
670
This exception is thrown by the library when a parse error occurs. Parse errors
671
can occur during the deserialization of JSON text, CBOR, MessagePack, as well
672
as when using JSON Patch.
673
674
Member @a byte holds the byte index of the last read character in the input
675
file.
676
677
Exceptions have ids 1xx.

------------------------------ | --------------- | -------------------------
681
json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
682
json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
683
json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
684
json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
685
json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
686
json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
687
json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
688
json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
689
json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
690
json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
691
json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
692
json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
693
694
@note For an input with n bytes, 1 is the index of the first character and n+1
695
      is the index of the terminating null byte or the end of file. This also
696
      holds true when reading a byte vector (CBOR or MessagePack).

756
json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
757
json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
758
json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.
759
json.exception.invalid_iterator.205 | iterator out of range | When an iterator for a primitive type (number, boolean, or string) is passed to an erase function, the iterator has to be the @ref begin() iterator, because it is the only way to address the stored value. All other iterators are invalid.
760
json.exception.invalid_iterator.206 | cannot construct with iterators from null | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) belong to a JSON null value and hence to not define a valid range.
761
json.exception.invalid_iterator.207 | cannot use key() for non-object iterators | The key() member function can only be used on iterators belonging to a JSON object, because other types do not have a concept of a key.
762
json.exception.invalid_iterator.208 | cannot use operator[] for object iterators | The operator[] to specify a concrete offset cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
763
json.exception.invalid_iterator.209 | cannot use offsets with object iterators | The offset operators (+, -, +=, -=) cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
764
json.exception.invalid_iterator.210 | iterators do not fit | The iterator range passed to the insert function are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
765
json.exception.invalid_iterator.211 | passed iterators may not belong to container | The iterator range passed to the insert function must not be a subrange of the container to insert to.
766
json.exception.invalid_iterator.212 | cannot compare iterators of different containers | When two iterators are compared, they must belong to the same container.
767
json.exception.invalid_iterator.213 | cannot compare order of object iterators | The order of object iterators cannot be compared, because JSON objects are unordered.
768
json.exception.invalid_iterator.214 | cannot get value | Cannot get value for iterator: Either the iterator belongs to a null value or it is an iterator to a primitive type (number, boolean, or string), but the iterator is different to @ref begin().

@brief the JSON type enumeration
949
950
This enumeration collects the different JSON types. It is internally used to
951
distinguish the stored values, and the functions @ref basic_json::is_null(),
952
@ref basic_json::is_object(), @ref basic_json::is_array(),
953
@ref basic_json::is_string(), @ref basic_json::is_boolean(),
954
@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
955
@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
956
@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
957
@ref basic_json::is_structured() rely on it.
958
959
@note There are three enumeration entries (number_integer, number_unsigned, and
960
number_float), because the library distinguishes these three types for numbers:
961
@ref basic_json::number_unsigned_t is used for unsigned integers,
962
@ref basic_json::number_integer_t is used for signed integers, and
963
@ref basic_json::number_float_t is used for floating-point numbers or to
964
approximate integers which do not fit in the limits of their respective type.
965
966
@sa @ref basic_json::basic_json(const value_t value_type) -- create a JSON
967
value with the default value for a given type
968
969

1894
Produces a stream of std::char_traits<char>::int_type characters from a
1895
std::istream, a buffer, or some other input type. Accepts the return of
1896
exactly one non-EOF character for future input. The int_type characters
1897
returned consist of all valid char values as positive values (typically
1898
unsigned char), plus an EOF value outside that range, specified by the value
1899
of the function std::char_traits<char>::eof(). This value is typically -1, but
1900
could be any arbitrary value which is not a valid char value.

    @brief scan a number literal
2919
2920
    This function scans a string according to Sect. 6 of RFC 7159.
2921
2922
    The function is realized with a deterministic finite state machine derived
2923
    from the grammar described in RFC 7159. Starting in state "init", the
2924
    input is read and used to determined the next state. Only state "done"
2925
    accepts the number. State "error" is a trap state to model errors. In the
2926
    table below, "anything" means any character but the ones listed before.

    The state machine is realized with one label per state (prefixed with
2941
    "scan_number_") and `goto` statements between them. The state machine
2942
    contains cycles, but any cycle can be left when EOF is read. Therefore,
2943
    the function is guaranteed to terminate.
2944
2945
    During scanning, the read bytes are stored in token_buffer. This string is
2946
    then converted to a signed integer, an unsigned integer, or a
2947
    floating-point number.
2948
2949
    @return token_type::value_unsigned, token_type::value_integer, or
2950
            token_type::value_float if number could be successfully scanned,
2951
            token_type::parse_error otherwise
2952
2953
    @note The scanner is independent of the current locale. Internally, the
2954
          locale's decimal point is used instead of `.` to work with the
2955
          locale-dependent converters.

@brief a template for a bidirectional iterator for the @ref basic_json class
5103
5104
This class implements a both iterators (iterator and const_iterator) for the
5105
@ref basic_json class.
5106
5107
@note An iterator is called *initialized* when a pointer to a JSON value has
5108
      been set (e.g., by a constructor or a copy assignment). If the iterator is
5109
      default-constructed, it is *uninitialized* and most methods are undefined.
5110
      **The library uses assertions to detect calls on uninitialized iterators.**
5111
5112
@requirement The class satisfies the following concept requirements:
5113
-
5114
[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
5115
  The iterator that can be moved can be moved in both directions (i.e.
5116
  incremented and decremented).

@brief a template for a reverse iterator class
5715
5716
@tparam Base the base iterator type to reverse. Valid types are @ref
5717
iterator (to create @ref reverse_iterator) and @ref const_iterator (to
5718
create @ref const_reverse_iterator).
5719
5720
@requirement The class satisfies the following concept requirements:
5721
-
5722
[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
5723
  The iterator that can be moved can be moved in both directions (i.e.
5724
  incremented and decremented).
5725
- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
5726
  It is possible to write to the pointed-to element (only if @a Base is
5727
  @ref iterator).

    @brief check whether a string is UTF-8 encoded
10250
10251
    The function checks each byte of a string whether it is UTF-8 encoded. The
10252
    result of the check is stored in the @a state parameter. The function must
10253
    be called initially with state 0 (accept). State 1 means the string must
10254
    be rejected, because the current byte is not allowed. If the string is
10255
    completely processed, but the state is non-zero, the string ended
10256
    prematurely; that is, the last byte indicated more bytes should have
10257
    followed.
10258
10259
    @param[in,out] state  the state of the decoding
10260
    @param[in,out] codep  codepoint (valid only if resulting state is UTF8_ACCEPT)
10261
    @param[in] byte       next byte to decode
10262
    @return               new state
10263
10264
    @note The function has been edited: a std::array is used.

@tparam ObjectType type for JSON objects (`std::map` by default; will be used
11158
in @ref object_t)
11159
@tparam ArrayType type for JSON arrays (`std::vector` by default; will be used
11160
in @ref array_t)
11161
@tparam StringType type for JSON strings and object keys (`std::string` by
11162

in @ref boolean_t)
11165
@tparam NumberIntegerType type for JSON integer numbers (`int64_t` by
11166
default; will be used in @ref number_integer_t)
11167
@tparam NumberUnsignedType type for JSON unsigned integer numbers (@c
11168
`uint64_t` by default; will be used in @ref number_unsigned_t)

default)
11173
@tparam JSONSerializer the serializer to resolve internal calls to `to_json()`
11174
and `from_json()` (@ref adl_serializer by default)
11175
11176
@requirement The class satisfies the following concept requirements:
11177
- Basic
11178
 - [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible):
11179
   JSON values can be default constructed. The result will be a JSON null
11180
   value.
11181
 - [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible):
11182
   A JSON value can be constructed from an rvalue argument.
11183
 - [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible):
11184
   A JSON value can be copy-constructed from an lvalue expression.
11185
 - [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable):
11186
   A JSON value van be assigned from an rvalue argument.
11187
 - [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable):
11188
   A JSON value can be copy-assigned from an lvalue expression.
11189
 - [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible):
11190
   JSON values can be destructed.
11191
- Layout
11192
 - [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType):
11193
   JSON values have
11194
   [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout):
11195
   All non-static data members are private and standard layout types, the
11196
   class has no virtual functions or (virtual) base classes.
11197
- Library-wide
11198
 - [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable):
11199
   JSON values can be compared with `==`, see @ref
11200
   operator==(const_reference,const_reference).
11201
 - [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable):
11202
   JSON values can be compared with `<`, see @ref
11203
   operator<(const_reference,const_reference).
11204
 - [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable):
11205
   Any JSON lvalue or rvalue of can be swapped with any lvalue or rvalue of
11206
   other compatible types, using unqualified function call @ref swap().
11207
 - [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer):
11208
   JSON values can be compared against `std::nullptr_t` objects which are used
11209
   to model the `null` value.
11210
- Container
11211
 - [Container](https://en.cppreference.com/w/cpp/named_req/Container):
11212
   JSON values can be used like STL containers and provide iterator access.
11213
 - [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer);
11214
   JSON values can be used like STL containers and provide reverse iterator
11215
   access.
11216
11217
@invariant The member variables @a m_value and @a m_type have the following
11218
relationship:
11219
- If `m_type == value_t::object`, then `m_value.object != nullptr`.
11220
- If `m_type == value_t::array`, then `m_value.array != nullptr`.
11221
- If `m_type == value_t::string`, then `m_value.string != nullptr`.
11222
The invariants are checked by member function assert_invariant().

    @brief a type for an object
11466
11467
    [RFC 7159](http://rfc7159.net/rfc7159) describes JSON objects as follows:
11468
    > An object is an unordered collection of zero or more name/value pairs,
11469
    > where a name is a string and a value is a string, number, boolean, null,
11470
    > object, or array.
11471
11472
    To store objects in C++, a type is defined by the template parameters
11473
    described below.
11474
11475
    @tparam ObjectType  the container to store objects (e.g., `std::map` or
11476
    `std::unordered_map`)
11477
    @tparam StringType the type of the keys or names (e.g., `std::string`).
11478
    The comparison function `std::less<StringType>` is used to order elements
11479
    inside the container.
11480
    @tparam AllocatorType the allocator to use for objects (e.g.,
11481
    `std::allocator`)
11482
11483
    #### Default type
11484
11485
    With the default values for @a ObjectType (`std::map`), @a StringType
11486
    (`std::string`), and @a AllocatorType (`std::allocator`), the default
11487
    value for @a object_t is:
11488
11489
    @code {.cpp}
11490
    std::map<
11491
      std::string, // key_type
11492
      basic_json, // value_type
11493
      std::less<std::string>, // key_compare
11494
      std::allocator<std::pair<const std::string, basic_json>> // allocator_type
11495
    >
11496
    @endcode
11497
11498
    #### Behavior
11499
11500
    The choice of @a object_t influences the behavior of the JSON class. With
11501
    the default type, objects have the following behavior:
11502
11503
    - When all names are unique, objects will be interoperable in the sense
11504
      that all software implementations receiving that object will agree on
11505
      the name-value mappings.
11506
    - When the names within an object are not unique, it is unspecified which
11507
      one of the values for a given key will be chosen. For instance,
11508
      `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
11509
      `{"key": 2}`.
11510
    - Internally, name/value pairs are stored in lexicographical order of the
11511
      names. Objects will also be serialized (see @ref dump) in this order.
11512
      For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
11513
      and serialized as `{"a": 2, "b": 1}`.
11514
    - When comparing objects, the order of the name/value pairs is irrelevant.
11515
      This makes objects interoperable in the sense that they will not be
11516
      affected by these differences. For instance, `{"b": 1, "a": 2}` and
11517
      `{"a": 2, "b": 1}` will be treated as equal.
11518
11519
    #### Limits
11520
11521
    [RFC 7159](http://rfc7159.net/rfc7159) specifies:
11522
    > An implementation may set limits on the maximum depth of nesting.
11523
11524
    In this class, the object's limit of nesting is not explicitly constrained.
11525
    However, a maximum depth of nesting may be introduced by the compiler or
11526
    runtime environment. A theoretical limit can be queried by calling the
11527
    @ref max_size function of a JSON object.
11528
11529
    #### Storage
11530
11531
    Objects are stored as pointers in a @ref basic_json type. That is, for any
11532
    access to object values, a pointer of type `object_t*` must be
11533
    dereferenced.
11534
11535
    @sa @ref array_t -- type for an array value
11536
11537
    @since version 1.0.0
11538
11539
    @note The order name/value pairs are added to the object is *not*
11540
    preserved by the library. Therefore, iterating an object may return
11541
    name/value pairs in a different order than they were originally stored. In
11542
    fact, keys will be traversed in alphabetical order as `std::map` with
11543
    `std::less` is used by default. Please note this behavior conforms to [RFC
11544
    7159](http://rfc7159.net/rfc7159), because any order implements the
11545
    specified "unordered" nature of JSON objects.

    To store objects in C++, a type is defined by the template parameter

    @tparam StringType  the container to store strings (e.g., `std::string`).
11610
    Note this container is used for keys/names in objects, see @ref object_t.
11611
11612
    #### Default type
11613
11614

    @endcode
11620
11621
    #### Encoding
11622
11623
    Strings are stored in UTF-8 encoding. Therefore, functions like
11624
    `std::string::size()` or `std::string::length()` return the number of
11625
    bytes in the string rather than the number of characters or glyphs.
11626
11627
    #### String comparison
11628
11629
    [RFC 7159](http://rfc7159.net/rfc7159) states:
11630
    > Software implementations are typically required to test names of object
11631
    > members for equality. Implementations that transform the textual
11632
    > representation into sequences of Unicode code units and then perform the

11689
11690
    This description includes both integer and floating-point numbers.
11691
    However, C++ allows more precise storage if it is known whether the number
11692
    is a signed integer, an unsigned integer or a floating-point number.
11693
    Therefore, three different types, @ref number_integer_t, @ref

    - The restrictions about leading zeros is not enforced in C++. Instead,
11711
      leading zeros in integer literals lead to an interpretation as octal
11712
      number. Internally, the value will be stored as decimal number. For
11713
      instance, the C++ integer literal `010` will be serialized to `8`.
11714
      During deserialization, leading zeros yield an error.
11715
    - Not-a-number (NaN) values will be serialized to `null`.

    #### Limits
11718
11719
    [RFC 7159](http://rfc7159.net/rfc7159) specifies:
11720
    > An implementation may set limits on the range and precision of numbers.
11721
11722
    When the default type is used, the maximal integer number that can be
11723
    stored is `9223372036854775807` (INT64_MAX) and the minimal integer number
11724
    that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers
11725
    that are out of range will yield over/underflow when used in a
11726
    constructor. During deserialization, too large or small integer numbers
11727
    will be automatically be stored as @ref number_unsigned_t or @ref
11728
    number_float_t.
11729
11730
    [RFC 7159](http://rfc7159.net/rfc7159) further states:
11731
    > Note that when such software is used, numbers that are integers and are
11732
    > in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are interoperable in the sense
11733
    > that implementations will agree exactly on their numeric values.
11734
11735
    As this range is a subrange of the exactly supported range [INT64_MIN,
11736
    INT64_MAX], this class's integer type is interoperable.
11737

    @brief a type for a number (unsigned)
11752
11753
    [RFC 7159](http://rfc7159.net/rfc7159) describes numbers as follows:
11754
    > The representation of numbers is similar to that used in most
11755
    > programming languages. A number is represented in base 10 using decimal
11756
    > digits. It contains an integer component that may be prefixed with an
11757
    > optional minus sign, which may be followed by a fraction part and/or an
11758
    > exponent part. Leading zeros are not allowed. (...) Numeric values that
11759
    > cannot be represented in the grammar below (such as Infinity and NaN)
11760
    > are not permitted.
11761
11762
    This description includes both integer and floating-point numbers.
11763
    However, C++ allows more precise storage if it is known whether the number
11764
    is a signed integer, an unsigned integer or a floating-point number.
11765
    Therefore, three different types, @ref number_integer_t, @ref
11766
    number_unsigned_t and @ref number_float_t are used.
11767
11768
    To store unsigned integer numbers in C++, a type is defined by the
11769
    template parameter @a NumberUnsignedType which chooses the type to use.
11770
11771
    #### Default type
11772
11773
    With the default values for @a NumberUnsignedType (`uint64_t`), the
11774
    default value for @a number_unsigned_t is:
11775
11776
    @code {.cpp}
11777
    uint64_t
11778
    @endcode
11779
11780
    #### Default behavior
11781
11782
    - The restrictions about leading zeros is not enforced in C++. Instead,
11783
      leading zeros in integer literals lead to an interpretation as octal
11784
      number. Internally, the value will be stored as decimal number. For
11785
      instance, the C++ integer literal `010` will be serialized to `8`.
11786
      During deserialization, leading zeros yield an error.
11787
    - Not-a-number (NaN) values will be serialized to `null`.

    > An implementation may set limits on the range and precision of numbers.
11793
11794
    When the default type is used, the maximal integer number that can be
11795
    stored is `18446744073709551615` (UINT64_MAX) and the minimal integer
11796
    number that can be stored is `0`. Integer numbers that are out of range
11797
    will yield over/underflow when used in a constructor. During
11798
    deserialization, too large or small integer numbers will be automatically
11799
    be stored as @ref number_integer_t or @ref number_float_t.
11800
11801
    [RFC 7159](http://rfc7159.net/rfc7159) further states:

11804
    > that implementations will agree exactly on their numeric values.
11805
11806
    As this range is a subrange (when considered in conjunction with the
11807
    number_integer_t type) of the exactly supported range [0, UINT64_MAX],
11808
    this class's integer type is interoperable.

11843

11845

    double
11849
    @endcode
11850

    #### Default behavior
11852
11853
    - The restrictions about leading zeros is not enforced in C++. Instead,
11854
      leading zeros in floating-point literals will be ignored. Internally,
11855
      the value will be stored as decimal number. For instance, the C++
11856
      floating-point literal `01.2` will be serialized to `1.2`. During
11857
      deserialization, leading zeros yield an error.
11858
    - Not-a-number (NaN) values will be serialized to `null`.
11859
11860
    #### Limits
11861
11862
    [RFC 7159](http://rfc7159.net/rfc7159) states:
11863
    > This specification allows implementations to set limits on the range and
11864
    > precision of numbers accepted. Since software that implements IEEE
11865

    > that expect no more precision or range than these provide, in the sense
11868
    > that implementations will approximate JSON numbers within the expected
11869
    > precision.
11870
11871
    This implementation does exactly follow this approach, as it uses double
11872
    precision floating-point numbers. Note values smaller than
11873
    `-1.79769313486232e+308` and values greater than `1.79769313486232e+308`

11916
11917
    The actual storage for a JSON value of the @ref basic_json class. This

11919
    defined in @ref value_t.

    array     | array           | pointer to @ref array_t
11925
    string    | string          | pointer to @ref string_t

    @brief per-element parser callback type
12142
12143
    With a parser callback function, the result of parsing a JSON text can be
12144
    influenced. When passed to @ref parse, it is called on certain events
12145
    (passed as @ref parse_event_t via parameter @a event) with a set recursion
12146
    depth @a depth and context JSON value @a parsed. The return value of the
12147
    callback function is a boolean indicating whether the element that emitted
12148
    the callback shall be kept or not.
12149
12150
    We distinguish six scenarios (determined by the event type) in which the
12151
    callback function can be called. The following table describes the values
12152
    of the parameters @a depth, @a event, and @a parsed.
12153
12154
    parameter @a event | description | parameter @a depth | parameter @a parsed
12155
    ------------------ | ----------- | ------------------ | -------------------
12156
    parse_event_t::object_start | the parser read `{` and started to process a JSON object | depth of the parent of the JSON object | a JSON value with type discarded
12157
    parse_event_t::key | the parser read a key of a value in an object | depth of the currently parsed JSON object | a JSON string containing the key
12158
    parse_event_t::object_end | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object | the parsed JSON object
12159
    parse_event_t::array_start | the parser read `[` and started to process a JSON array | depth of the parent of the JSON array | a JSON value with type discarded
12160
    parse_event_t::array_end | the parser read `]` and finished processing a JSON array | depth of the parent of the JSON array | the parsed JSON array
12161
    parse_event_t::value | the parser finished reading a JSON value | depth of the value | the parsed JSON value

12164
12165
    Discarding a value (i.e., returning `false`) has different effects
12166
    depending on the context in which function was called:
12167
12168
    - Discarded values in structured types are skipped. That is, the parser
12169
      will behave as if the discarded value was never read.
12170
    - In case a value outside a structured type is skipped, it is replaced
12171
      with `null`. This case happens if the top-level element is skipped.
12172
12173
    @param[in] depth  the depth of the recursion during parsing
12174
12175
    @param[in] event  an event of type parse_event_t indicating the context in
12176
    the callback function has been called
12177
12178
    @param[in,out] parsed  the current intermediate parse result; note that
12179
    writing to this value has no effect for parse_event_t::key events
12180
12181
    @return Whether the JSON value which called the function during parsing
12182
    should be kept (`true`) or not (`false`). In the latter case, it is either
12183
    skipped completely or replaced by an empty discarded object.

    @brief create a container (array or object) from an initializer list
12402
12403
    Creates a JSON value of type array or object from the passed initializer
12404
    list @a init. In case @a type_deduction is `true` (default), the type of
12405
    the JSON value to be created is deducted from the initializer list @a init
12406
    according to the following rules:
12407
12408
    1. If the list is empty, an empty JSON object value `{}` is created.
12409
    2. If the list consists of pairs whose first element is a string, a JSON
12410
       object value is created where the first elements of the pairs are
12411
       treated as keys and the second elements are as values.
12412
    3. In all other cases, an array is created.
12413
12414
    The rules aim to create the best fit between a C++ initializer list and
12415
    JSON values. The rationale is as follows:
12416
12417
    1. The empty initializer list is written as `{}` which is exactly an empty
12418
       JSON object.
12419
    2. C++ has no way of describing mapped types other than to list a list of
12420
       pairs. As JSON requires that keys must be of type string, rule 2 is the
12421
       weakest constraint one can pose on initializer lists to interpret them
12422
       as an object.
12423
    3. In all other cases, the initializer list could not be interpreted as
12424
       JSON object type, so interpreting it as JSON array type is safe.
12425
12426
    With the rules described above, the following JSON values cannot be
12427
    expressed by an initializer list:
12428
12429
    - the empty array (`[]`): use @ref array(initializer_list_t)
12430
      with an empty initializer list in this case
12431
    - arrays whose elements satisfy rule 2: use @ref
12432
      array(initializer_list_t) with the same initializer list
12433
      in this case
12434
12435
    @note When used without parentheses around an empty initializer list, @ref
12436
    basic_json() is called instead of this function, yielding the JSON null
12437
    value.
12438
12439
    @param[in] init  initializer list with JSON values
12440
12441
    @param[in] type_deduction internal parameter; when set to `true`, the type
12442
    of the JSON value is deducted from the initializer list @a init; when set
12443
    to `false`, the type provided via @a manual_type is forced. This mode is
12444
    used by the functions @ref array(initializer_list_t) and
12445
    @ref object(initializer_list_t).
12446
12447
    @param[in] manual_type internal parameter; when @a type_deduction is set
12448
    to `false`, the created JSON value will use the provided type (only @ref
12449
    value_t::array and @ref value_t::object are valid); when @a type_deduction
12450
    is set to `true`, this parameter has no effect
12451
12452
    @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
12453
    `value_t::object`, but @a init contains an element which is not a pair
12454
    whose first element is a string. In this case, the constructor could not
12455
    create an object. If @a type_deduction would have be `true`, an array
12456
    would have been created. See @ref object(initializer_list_t)
12457
    for an example.

          removes the closing marker. Parameter @a use_type further checks
17619
          whether all elements of a container have the same type and adds the
17620
          type marker to the beginning of the container. The @a use_type
17621
          parameter must only be used together with @a use_size = true. Note
17622
          that @a use_size = true alone may result in larger representations -
17623
          the benefit of this parameter is that the receiving side is

17993

      is returned. All indices between the current maximum and the given

18209
18210
    [JSON Patch](http://jsonpatch.com) defines a JSON document structure for

18215
    @param[in] json_patch  JSON patch document
18216
    @return patched document
18217
18218
    @note The application of a patch is atomic: Either all operations succeed
18219
          and the patched document is returned or an exception is thrown. In
18220
          any case, the original value is not changed: the patch is applied
18221
          to a copy of the value.
18222
18223
    @throw parse_error.104 if the JSON patch does not consist of an array of
18224
    objects
18225
18226
    @throw parse_error.105 if the JSON patch is malformed (e.g., mandatory
18227
    attributes are missing); example: `"operation add must have member path"`
18228
18229
    @throw out_of_range.401 if an array index is out of range.
18230
18231
    @throw out_of_range.403 if a JSON pointer inside the patch could not be
18232
    resolved successfully in the current JSON value; example: `"key baz not
18233
    found"`
18234
18235
    @throw out_of_range.405 if JSON pointer has no parent ("add", "remove",
18236
    "move")

18238

    @note Currently, only `remove`, `add`, and `replace` operations are
18534
          generated.

    @brief applies a JSON Merge Patch
18690
18691
    The merge patch format is primarily intended for use with the HTTP PATCH
18692
    method as a means of describing a set of modifications to a target
18693
    resource's content. This function applies a merge patch to the current
18694
    JSON value.
18695
18696
    The function implements the following algorithm from Section 2 of
18697
    [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
18698
18699
    ```
18700
    define MergePatch(Target, Patch):
18701
      if Patch is an Object:
18702
        if Target is not an Object:
18703
          Target = {} // Ignore the contents and set it to an empty Object
18704
        for each Name/Value pair in Patch:
18705
          if Value is null:
18706
            if Name exists in Target:
18707
              remove the Name/Value pair from Target
18708
          else:
18709
            Target[Name] = MergePatch(Target[Name], Value)
18710
        return Target
18711
      else:
18712
        return Patch
18713
    ```
18714
18715
    Thereby, `Target` is the current object; that is, the patch is applied to
18716
    the current value.
18717
18718
    @param[in] patch  the patch to apply
18719
18720
    @complexity Linear in the lengths of @a patch.
